Does COVID-19 psychological fatigue exist? Results of three online cross-sectional studies conducted in Spain from April 2020 to March 2021.

Background: A previously published meta-analysis found that about one-third of the general population experienced some mental health problem during the early phase of the COVID-19 pandemic, potentially leading to a late mental health crisis. We aimed to describe the acute, short-term, and long-term effects of the COVID-19 pandemic on mental health. Methods: A one-year online survey (S) was conducted in Spain (April 2020 - March 2021). We recruited 18 180 subjects using a virtual respondent-driven snowball sampling method (S1 April 2020, n = 6108; S2 October-November 2020, n = 6418; S3 March 2021, n = 5654). Participants completed the Spanish Depression, Anxiety, and Stress Scale (DASS-21). Results: Overall, our results suggest a progressive increase in the prevalence of anxiety and stress throughout the pandemic waves and relative stability of depression. Women had a greater probability of having depression, anxiety, or stress than men in each survey (P < 0.001). The youngest group (aged 18-24) reported a higher probability (P < 0.05) of having depression, anxiety, or stress than the older groups in S1 and S2. Middle-aged people (25-59) had a greater probability of being a case in the DASS-21 scales than the oldest group (60+), except for depression in men (P = 0.179). In S3, the trend changed: the youngest group showed a decrease in depression and stress while the oldest group showed a dramatic increase (anxiety: men = 664.5%, women = 273.52%; stress: men = 786%, women = 431.37%). Conclusions: It is plausible to conclude that COVID-19 psychological fatigue exists, especially in middle-aged and older adults. Strategies to assist people who have fewer coping skills should be implemented in the near future.

Tabaquismo en pacientes hospitalizados. Una gran oportunidad / Smoking in hospitalized patients. A great opportunity

El objetivo de este estudio es conocer las características de los fumadores ingresados en diferentes servicios médicos y quirúrgicos en un hospital universitario y la percepción de los pacientes respecto a la necesidad de una intervención especializada. La muestra comprende un total de 307 pacientes (edad media de 59,4 años), siendo un 40% (n = 123) no fumadores, 42,7% (n = 131) exfumadores, y un 17,3% (n = 53) fumadores. El consumo medio de los fumadores era de 22,2 cigarrillos/día y la gravedad de la dependencia a la nicotina evaluado con el test de Fagerström sobrepasaba los 5 puntos en más de la mitad de la muestra. Por otra parte, el 77,7% había realizado al menos un intento previo de abandono del consumo de tabaco. Casi la totalidad de la muestra (89,9%) de los fumadores y ex fumadores consideraba necesario desarrollar programas de tratamiento del tabaquismo en la hospitalización. Finalmente se argumenta la importancia del contexto hospitalario como oportunidad para abordar la cesación del hábito tabáquico. Los datos obtenidos en el presente estudio permitirán enfocar más adecuadamente el manejo de estos pacientes y optimizar los recursos.(AU)

The objective of this study is to describe the characteristics of smokers admitted to different medical and surgical services in a university hospital and the perception of patients regarding the need for a specialized intervention. The sample comprises a total of 307 patients (mean age of 59.4 years), being 40% (n = 123) nonsmokers, 42.7% (n = 131) ex-smokers, and 17.3% (n = 53) smokers. The average consumption of smokers was 22.2 cigarettes / day and the severity of nicotine dependence evaluated with the Fagerström test exceeded 5 points in more than half of the sample. On the other hand, 77.7% had made at least one previous attempt to quit tobacco use. Almost the entire sample (89.9%) of smokers and ex-smokers considered it necessary to develop tobacco treatment programs during hospitalization. Finally, the importance of the hospital context is argued as an opportunity to address the cessation of smoking. The data obtained in this study will allow focusing more appropriately on the management of these patients and optimizing resources.(AU)

Tratamientos Psicológicos Empíricamente Apoyados Para Adultos: Una Revisión Selectiva / Evidence-Based Psychological Treatments for Adults: A Selective Review

Antecedentes: los tratamientos psicológicos han mostrado su efi cacia, efectividad y efi ciencia para el abordaje de los trastornos mentales; no obstante, considerando el conocimiento científi co generado en los últimos años, no se dispone de trabajos de actualización en español sobre cuáles son los tratamientos psicológicos con respaldo empírico. El objetivo fue realizar una revisión selectiva de los principales tratamientos psicológicos empíricamente apoyados para el abordaje de trastornos mentales en personas adultas. Método: se recogen niveles de evidencia y grados de recomendación en función de los criterios propuestos por el Sistema Nacional de Salud de España (en las Guías de Práctica Clínica) para diferentes trastornos psicológicos. Resultados: los resultados sugieren que los tratamientos psicológicos disponen de apoyo empírico para el abordaje de un amplio elenco de trastornos psicológicos. El grado de apoyo empírico oscila de bajo a alto en función del trastorno psicológico analizado. La revisión sugiere que ciertos campos de intervención necesitan una mayor investigación. Conclusiones: a partir de esta revisión selectiva, los profesionales de la psicología podrán disponer de información rigurosa y actualizada que les permita tomar decisiones informadas a la hora de implementar aquellos procedimientos psicoterapéuticos empíricamente fundamentados en función de las características de las personas que demandan ayuda. (AU)

Background: Psychological treatments have shown their effi cacy, effectiveness, and effi ciency in dealing with mental disorders. However, considering the scientifi c knowledge generated in recent years, in the Spanish context, there are no updating studies about empirically supported psychological treatments. The main goal was to carry out a selective review of the main empirically supported psychological treatments for mental disorders in adults. Method: Levels of evidence and degrees of recommendation were collected based on the criteria proposed by the Spanish National Health System (Clinical Practice Guidelines) for different psychological disorders. Results: The results indicate that psychological treatments have empirical support for the approach to a wide range of psychological disorders. These levels of empirical evidence gathered range from low to high depending on the psychological disorder analysed. The review indicates the existence of certain fi elds of intervention that need further investigation. Conclusions: Based on this selective review, psychology professionals will be able to have rigorous, up-to-date information that allows them to make informed decisions when implementing empirically based psychotherapeutic procedures based on the characteristics of the people who require help.

Early psychological impact of the 2019 coronavirus disease (COVID-19) pandemic and lockdown in a large Spanish sample.

BACKGROUND: Epidemic outbreaks have significant impact on psychological well-being, increasing psychiatric morbidity among the population. We aimed to describe the early psychological impact of COVID-19 and its contributing factors in a large Spanish sample, globally and according to mental status (never mental disorder NMD, past mental disorder PMD, current mental disorder CMD). METHODS: An online questionnaire was conducted between 19 and 26 March, five days after the official declaration of alarm and the lockdown order. Data included sociodemographic and clinical information and the DASS-21 and IES questionnaires. We analysed 21 207 responses using the appropriate descriptive and univariate tests as well as binary logistic regression to identify psychological risk and protective factors. RESULTS: We found a statistically significant gradient in the psychological impact experienced in five domains according to mental status, with the NMD group being the least affected and the CMD group being the most affected. In the three groups, the depressive response was the most prevalent (NMD = 40.9%, PMD = 51.9%, CMD = 74.4%, F = 1011.459, P < 0.001). Risk factors were female sex and classification as a case in any psychological domain. Protective factors were younger age and ability to enjoy free time. Variables related to COVID-19 had almost no impact except for having COVID-19 symptoms, which was a risk factor for anxiety in all three groups. CONCLUSIONS: Our results can help develop coping strategies addressing modifiable risk and protective factors for each mental status for early implementation in future outbreaks.

Los cambios estructurales de la retina, ¿nuevos biomarcadores de los trastornos mentales? Una revisión sistemática y síntesis temática de la literatura / Could structural changes in the retinal layers be a new biomarker of mental disorders? A systematic review and thematic synthesis

Recientemente se ha planteado que las alteraciones de las capas de la retina podrían ser un biomarcador de determinados trastornos mentales, al derivar esta de la misma capa embrionaria que el cerebro y estar conectada con este a través del nervio óptico. El objeto del presente artículo es ofrecer una revisión sistemática de la literatura y una síntesis temática sobre el estado actual de las alteraciones de las capas de la retina identificadas mediante tomografía de coherencia óptica en los pacientes con esquizofrenia, trastorno bipolar y depresión mayor. Para ello se realizó una búsqueda sistemática de la literatura, la lectura crítica de los artículos seleccionados y la síntesis temática de los resultados. Los pacientes con esquizofrenia son los que presentan más alteraciones, seguidos de los pacientes con trastorno bipolar, siendo muy escasos los hallazgos en la depresión. La capa de fibras nerviosas de la retina es la capa retiniana con más alteraciones en la esquizofrenia y en el trastorno bipolar, mientras que ningún estudio en depresión mayor encontró alteraciones en ella. De los parámetros clínicos, la duración de la enfermedad correlaciona significativa e inversamente con el grosor de las distintas capas en todos los trastornos. A la hora de interpretar estos datos es necesario tener en cuenta las limitaciones y diferencias de los estudios, especialmente el tiempo medio de evolución de los trastornos. Dado que este era muy diferente entre los 3 trastornos (más del doble en el caso de la esquizofrenia respecto a la depresión mayor), las diferencias en los resultados encontrados podrían deberse más al efecto del tiempo de evolución que al trastorno en sí. En conclusión, los hallazgos de la tomografía de coherencia óptica son esperanzadores, ya que podrían proporcionar biomarcadores de la neurodegeneración y/o neuroprogresión tanto de la esquizofrenia como del trastorno bipolar

It has recently been suggested that alterations of the layers of the retina could be a biomarker of specific mental disorders since they originate in the same embryonic layer as the brain and both are interconnected through the optic nerve. The purpose of this article is to offer a systematic review of the literature and a thematic synthesis on the current state of the alterations of the retina layers identified by optical coherence tomography in patients with schizophrenia, bipolar disorder and major depression. For this purpose, we performed a bibliographic search, a systematic review of the studies and a thematic synthesis of the reported findings. Patients with schizophrenia have more abnormal findings followed by patients with bipolar disorder, with very few findings in depression. The nerve fiber layer is the retinal layer with more abnormal findings both in schizophrenia and in bipolar disorder, while no study in major depression found alterations in it. Of the clinical parameters, the duration of the illness correlates significantly and inversely with the thickness of the different layers in all disorders. When interpreting these data, it is necessary to take into account the limitations and differences of the studies, especially the mean length of the disorders. Given that this was very different among the 3 disorders (more than doubled in the case of schizophrenia respect to major depression), the differences in the results found could be due more to the effect of the length of illness than to the disorder itself. In summary, optical coherence tomography findings are promising, since they could provide biomarkers of neurodegeneration and/or neuroprogression of both schizophrenia and bipolar disorder

Validación española de la escala de evaluación de los síntomas negativos-16 (NSA-16) en pacientes con esquizofrenia / Spanish validation of the Negative Symptom Assessment-16 (NSA-16) in patients with schizophrenia

Introducción: Los síntomas negativos prevalecen en la esquizofrenia y están asociados con un peor resultado. La validación de nuevos instrumentos psicométricos podría contribuir a una mejor evaluación de los síntomas negativos y a un avance en su tratamiento. La escala de evaluación de los síntomas negativos-16 (Negative Symptom Assessment-16 [NSA-16]) ha demostrado adecuadas propiedades psicométricas, pero existe la necesidad de validarla en otros idiomas diferentes del inglés. Este estudio tiene como objetivo examinar las propiedades psicométricas de la versión española de la NSA-16 (Sp-NSA-16). Material y método: Estudio observacional, transversal de validación en una muestra de 123 pacientes con diagnóstico de esquizofrenia en tratamiento ambulatorio. Evaluación: NSA-16, PANSS, HDRS, ICG-ESQ y PSP. Resultados: Los resultados muestran unas adecuadas propiedades psicométricas, alta consistencia interna (alfa de Cronbach=0,86), validez convergente (escala negativa de la PANSS, factor negativo de Marder de la PANSS y escala de los síntomas negativos de la ICG: valores r entre 0,81 y 0,94) y validez divergente (escala positiva de la PANSS y HDRS: valores r entre 0,10 y 0,34). Además, la NSA-16 también muestra validez discriminante (curva ROC=0,97; IC 95%=0,94 a 1,00; 94,3% de sensibilidad y 83,3% de especificidad). Conclusiones: La Sp-NSA-16 es fiable y válida para medir los síntomas negativos en pacientes con esquizofrenia. Proveemos a los clínicos españoles con una nueva herramienta para la práctica clínica e investigación. Sin embargo, es necesario proporcionar más información sobre su fiabilidad interevaluadores

Introduction: Negative symptoms are prevalent in schizophrenia and associated with a poorer outcome. Validated newer psychometric instruments could contribute to better assessment and improved treatment of negative symptoms. The Negative Symptom Assessment-16 (NSA-16) has been shown to have strong psychometric properties, but there is a need for validation in non-English languages. This study aimed to examine the psychometric properties of a Spanish version of the NSA-16 (Sp-NSA-16). Material and method: Observational, cross-sectional validation study in a sample of 123 outpatients with schizophrenia. Assessments: NSA-16, PANSS, HDRS, CGI-SCH and PSP. Results: The results indicate appropriate psychometric properties, high internal consistency (Cronbach's alpha=0.86), convergent validity (PANSS negative scale, PANSS Marder Negative Factor and CGI-negative symptoms r values between 0.81 and 0.94) and divergent validity (PANSS positive scale and the HDRS r values between 0.10 and 0.34). In addition, the NSA-16 also exhibited discriminant validity (ROC curve=0.97, 95% CI=0.94 to 1.00; 94.3% sensitivity and 83.3% specificity). Conclusions: The Sp-NSA-16 is reliable and valid for measuring negative symptoms in patients with schizophrenia. This provides Spanish clinicians with a new tool for clinical practice and research. However, it is necessary to provide further information about its inter-rater reliability

Métodos de exploración de la función cognitiva en la práctica clínica / Assessment of cognitive function in daily clinical practice

Los síntomas cognitivos son uno de los criterios diagnósticos de la depresión y, sin embargo, no existe en la actualidad un método gold standard para su detección y evaluación. En el presente artículo se revisan los métodos de evaluación existentes en la actualidad, desde la historia clínica a la evaluación mediante instrumentos de evaluación psicométrica. Dentro de los instrumentos de evaluación psicométrica se diferencian 3 tipos de medidas: a) valoradas por el clínico (CROM, clinician rated outcome measures); b) valoradas por el paciente (PROM, patient reported outcome measures), y c) mixtas, valoradas por el clínico y por el paciente (CROM + PROM). La tendencia en la actualidad es utilizar medidas de evaluación que combinen ambos tipos de información: objetiva, proporcionada por el clínico basándose en la observación de la ejecución de determinadas tareas del paciente, y subjetiva, basada en las dificultades autopercibidas por el paciente (AU)

Cognitive symptoms are one of the diagnostic criteria for depression. However, there is currently no gold standard for their identification and assessment. This article reviews current assessment methods, including history-taking and psychometric assessment. There are 3 types of psychometric assessment tools: a) clinicianrated outcome measures (CROM); b) patient-reported outcome measures (PROM), and c) mixed, assessed by both the clinician and patient (CROM + PROM). The current tendency is to use assessment methods that combine both types of information: objective, provided by the clinician and based on observation of the patient’s performance of specific tasks, and subjective, based on the patient's self-perceived difficulties (AU)

Psychometric properties of a Spanish-version of the Schizophrenia Objective Functioning Instrument (Sp-SOFI) / Propiedades psicométricas de la versión en español del Instrumento de Funcionamiento Objetivo para la Esquizofrenia (Sp-SOFI)

The Schizophrenia Objective Functioning Instrument (SOFI) is an intervieweradministered scale designed to objectively assess the actual level of patient functioning and to measure community functioning related to cognitive impairment and psychopathology. The aim was to examine the psychometric properties of the Spanish version of the SOFI (Sp-SOFI) in a sample of 155 Spanish outpatients with schizophrenia disorder. The instruments applied were SpSOFI, Positive and Negative Syndrome Scale (PANSS), Clinical Global Impression-Schizophrenia Scale (CGI-SCH), Personal and Social Performance Scale (PSP), and Global Assessment of Functioning (GAF). The discrimination indexes of the Sp-SOFI items range from .21 to .77. Exploratory factor analysis showed an essentially one-dimensional structure. Cronbach’s alpha was .93. Test-retest reliability for the Sp-SOFI total score was .87 (p < .001). The canonical correlation between SP-SOFI domains and PSP dimensions was .83. The multiple correlation coefficient between Sp-SOFI domains and GAF score was .84. Sp-SOFI scores were significantly different between high and low scores on the PANSS scales (p < .001). Sp-SOFI measures discriminated among patients with doubtful, mild, moderate, and severe schizophrenia disorder according to CGI-SCH scales (p < .001). New evidence about the validity of the SOFI was provided. The Sp-SOFI is a reliable and valid tool for using in clinical practice (AU)

Psychometric evaluation of the negative syndrome of schizophrenia.

In this paper, we reviewed the available instruments for assessing the negative syndrome of schizophrenia, describing their strengths and weaknesses. Current instruments were classified into two categories according to their content validity and assessment approach as first- or second-generation instruments. The BPRS, SANS, the SENS and the PANSS belong to the first generation, while the BNSS, the CAINS and the MAP-SR belong to the second generation. The NSA can be considered a transitional instrument between the two. First-generation instruments have more content validity problems than second-generation instruments do, as they do not accurately reflect the currently accepted negative syndrome (they do not include all negative symptoms and signs or they include symptoms from other dimensions). They also have more problems relative to the use of behavioural referents instead of internal experiences of deficits when assessing symptoms, which may lead to measuring functioning instead of negative symptoms. Further research needs to be done in this area in order to ensure the evaluation of primary negative symptoms and internal experiences involved in negative symptoms rather than external behaviours.

Desarrollo de la versión española de la Escala Breve para la Evaluación de la Capacidad Funcional [Sp-UPSA-Brief] para pacientes con esquizofrenia y trastorno bipolar / Development of the Spanish Brief-version of the University of California Performance Skills Assessment (Sp-UPSA-Brief) in patients with schizophrenia and bipolar disorder

Introducción. En los pacientes con trastornos mentales graves, la medición de los desenlaces clínicos debería incluir como mínimo la evaluación de los síntomas, la cognición, la funcionalidad y la calidad de vida. Desde un punto de vista pragmático, los instrumentos abreviados y eficientes presentan mayor potencial en cuanto a utilidad y validez clínica. Nuestro objetivo fue desarrollar la versión española de la escala UPSA abreviada (SP-UPSA-Brief). Material y métodos. Estudio multicéntrico de diseño naturalista y con 6 meses de seguimiento. Se evaluaron 139 pacientes con esquizofrenia, 57 con trastorno bipolar y 31 controles mediante el empleo de la Sp-UPSA, la CGI-S, la GAF, y la PSP. Se realizó un modelo de regresión lineal multivariante para identificar las subescalas candidatas para la Sp-UPSA-Brief. Resultados. Según el modelo de regresión por pasos para los pacientes con esquizofrenia las subescalas de comunicación y de transporte de la Sp-UPSA fueron la primera y la segunda introducidas, con p < 0,0001 (R2 = 0,88, modelo df = 2, F = 395,05). En los pacientes con trastorno bipolar las subescalas de transporte y de comunicación de la Sp-UPSA se introdujeron en primer y segundo lugar, respectivamente, con p < 0,0001 (R2 = 0,87, modelo df = 2, F = 132,32). El alfa de Cronbach fue de 0,78 para la esquizofrenia y de 0,64 en pacientes bipolares. El test-retest fue de 0,66 y de 0,64 (p < 0,0001), respectivamente. Los coeficientes de correlación de Pearson entre la Sp-UPSA y la Sp-UPSA-Brief fueron de 0,93 para la esquizofrenia y de 0,92 para los pacientes bipolares (p < 0,0001). La Sp-UPSA-Brief discriminó entre los pacientes y los controles. En los pacientes con esquizofrenia también discriminó entre los grados de gravedad de la enfermedad de acuerdo con las puntuaciones CGI-S. Conclusiones. La escala Sp-UPSA-Brief es un instrumento alternativo, válido y fiable, para la evaluación de la capacidad funcional. Su formato abreviado lo convierte en un instrumento más útil a la hora de evaluar la capacidad funcional de los pacientes con trastornos mentales graves, sobre todo en la práctica clínica diaria (AU)

Introduction. In patients with severe mental disorders outcome measurement should include symptoms, cognition, functioning and quality of life at least. Shorter and efficient instruments have greater potential for pragmatic and valid clinical utility. Our aim was to develop the Spanish UPSA Brief scale (Sp-UPSA-Brief). Material and methods. Naturalistic, 6-month follow-up, multicentre study. 139 patients with schizophrenia, 57 with bipolar disorder and 31 controls were evaluated using the Sp-UPSA, CGI-S, GAF, and PSP. We conducted a multivariate linear regression model to identify candidate subscales for the Sp-UPSA-Brief. Results. The stepwise regression model for patients with schizophrenia showed that communication and transportation Sp-UPSA subscales entered first and second at p < 0.0001 (R2 = 0.88, model df = 2, F = 395.05). In patients with bipolar disorder transportation and communication Sp-UPSA subscales entered first and second at p < 0.0001 (R2 = 0.87, model df = 2, F = 132.32). Cronbach's alpha was 0.78 in schizophrenia and 0.64 in bipolar patients. Test-retest was 0.66 and 0.64 (p < 0.0001) respectively. Pearson correlation coefficients between Sp-UPSA and Sp-UPSA-Brief were 0.93 for schizophrenia and 0.92 for bipolar patients (p < 0.0001).The Sp-UPSA-Brief discriminated between patients and controls. In schizophrenia patients it also discriminated among different levels of illness severity according to CGI-S scores. Conclusion. The Sp-UPSA-Brief is an alternate instrument to evaluate functional capacity that is valid and reliable. Having a shorter instrument makes it more feasible to assess functional capacity in patients with severe mental disorders, especially in everyday clinical practice (AU)

CONCLUSION: The Sp-UPSA-Brief is an alternate instrument to evaluate functional capacity that is valid and reliable. Having a shorter instrument makes it more feasible to assess functional capacity in patients with severe mental disorders, especially in everyday clinical practice.

Long term outcomes of pharmacological treatments for opioid dependence: does methadone still lead the pack?

The aim of this review was to update and summarize the scientific knowledge on the long term outcomes of the different pharmacological treatment options for opioid dependence currently available and to provide a critical discussion on the different treatment options based on these results. We performed a literature search using the PubMed databases and the reference lists of the identified articles. Data from research show that the three pharmacological options reviewed are effective treatments for opioid dependence with positive long term outcomes. However, each one has its specific target population and setting. While methadone and buprenorphine are first line options, heroin-assisted treatment is a second line option for those patients refractory to treatment with methadone with concomitant severe physical, mental, social and/or functional problems. Buprenorphine seems to be the best option for use in primary care offices. The field of opioid dependence treatment is poised to undergo a process of reinforcement and transformation. Further efforts from researchers, clinicians and authorities should be made to turn new pharmacological options into clinical reality and to overcome the structural and functional obstacles that maintenance programmes face in combatting opioid dependence.
